Hello,
I've bought a damaged Forester XT Premium 2015 and I'm starting the recovery process. While I'm waiting for the body parts I'm focusing in putting the engine to run. First I sent the car to an mechanic and he told me that the engine ecu is not responding, because his scanner wasn't able to connect to the vehicle to read any fault codes. After that I sent the vehicle to the Subaru dealership and they confirmed that the ecu is damaged and needs to be replaced.
I think that diagnostic is weird, because the crash didn't affect much the engine or any electronic parts.
Does anyone know about something that might be 'blocking' the access to the ecu, maybe due to the crash? Something like the air bag system blocking the engine or something?
The dealership is asking me $2000 for a new ECU, while I found an used for around $600. Is it possible to just replace the original ECU by a similar from another car? Is there any kind of locks, keys, passwords or something that might block the communication between the ECUs?
Regarding the ECU partnumbers, mine is: 22765AH011, while the used I found is 22765AH010. All the other parts I found in the stores are not equal, but similar partnumbers: 22765AG970, 22765AG973, 22765AH510.

Are all these ECUs the same, but with different 'software versions'? Is it possible to know if they are compatible? All of them are for the same vehicle version: Forester XT Premium 2015.
Thanks in advance for any enlightenment!!
